To better protect your privacy and security, Firefox includes permissions that control whether websites can access apps and services on your local network and local device. This change stops websites from exploiting them without your knowledge.
This feature is experimental and is being introduced to the Firefox user base through a progressive rollout. It may not yet be available to all users.
Why is Firefox adding these permissions?
Websites can attempt to access your personal device — such as your computer or local network — and connected devices — such as routers, printers and local web servers — without your permission. Malicious sites have used these capabilities to track you or scan for vulnerable devices.
To keep you safe and help you stay in control of your data and devices, Firefox now asks for your permission when a site tries to connect to your device or local network.
What to expect when a site requests access
When a website tries to access your device or local network, Firefox will display a permission prompt similar to those for accessing your camera or microphone.
You can choose to:
- access for that visit
- access for that visit
You can also choose to have Firefox remember your decision for all future visits. You can change it anytime in your Settings.
What is considered ”device apps and services”?
"Device apps and services" are your personal computer and all the applications installed on it.
What is considered a "local network device"?
Local network devices are any hardware connected to the same local network as your device. This includes:
- Routers
- Printers
- File servers
- Smart TVs
- Media streamers
- IoT (Internet of Things) devices
Accessing these devices over the network could allow websites to interact with or retrieve data from them. A permission check helps prevent sites from doing so without your knowledge.
Manage access permissions to your device and local network
When a site tries to access other apps and services on your device or your local network, Firefox will show a permission prompt near the address bar, asking you to allow access.
